That's a really great app which has been around for a long time. I tried to make some things a little different.

For example emphasising on the three different types of data (class, homework, grading) with each having it's own view, but still showing all of them in the calendar to have a summary of what's going on. Sharing your calendar with Google Calendar, Outlook or similar also allows you to select which type of data you wanna share.

Or being able to set a repeat of any item, not just a class. So you can create for example a repeating quiz grading over several weeks.

There are more, smaller differences like you can enter extra-curricular events that to not belong to any course. Or have an attendance tracking where you can skip single classes and see an overview of skipped ones..
